I love Dragon Ball Z and as such there is much about this movie I was willing to overlook (Like Frieza somehow becoming 100 times stronger after 6 months of training) but the power level inconsistencies of Roshi, Gohan and Piccolo really let this movie down.

1. Master Roshi who has never had a power up on this show and as such should still have a power level below 1000, somehow being able to battle multiple Frieza henchman.

2. The Z crew struggling against the 1000 man Frieza army - by this stage in the show the Z fighters are so strong and fast that they should have been able to take all 1000 of them out in a matter of seconds.

3. Piccolo struggling against a single Frieza henchman whose power level was compared to Daddorio and Zarbons in the movie. Gohan had to go SS to beat him. If the henchman was that strong, why would they need Frieza back at all!! 4. Frieza in his weakest form managing to knock out Gohan with a single punch, yet after Frieza transforms to his 4th form (The one before Golden), Goku doesn't even need to go Super Saiyan to keep up with him.

Here's what they should have done to make it a good movie.

1. Have Piccolo, Gohan, Tien and Krillin obliterate Frieza's henchman with ease. Leave Roshi at home, or give him a one on one battle against a weak henchman.

2. Have Piccolo and Gohan fight Frieza in his 4th form, prob commenting on how they were heaps stronger and that Frieza doesn't stand a chance.

3. Then after taking a small beating, have Frieza turn golden and kick the crap out of Piccolo and Gohan.

4. Then the final battle, but for a change, let Vegeta get the glory. Just once I would like to see that.
